摘      要：Background:This study aimed to investigate the value of high field-strength intraoperative magnetic resonance imaging(iMRI)-guided stereotactic biopsy in the surgery of intracranial space-occupying ***:A total of 87 patients who underwent stereotactic biopsy of intracranial lesions in the Peking University International Hospital from March 2016 to August 2018 were retrospectively surveyed;among these,50 patients underwent MRI-guided stereotactic biopsy using the Leksell frame(iMRI group)and 37 cases received traditional stereotactic biopsy using the Leksell frame(control group).The accuracy rates and complications of the two groups were ***:A 100%positive diagnosis was observed in all cases(n=50)in the iMRI *** 4 cases,the biopsy site was clearly found to have deviated from the target point,and the biopsy was performed *** control group had 33 cases(86.5%)with positive *** severe complications like neural functional deficit were observed in the iMRI group,while two patients developed bleeding at the puncture site(1 case receiving surgery to remove the hematoma)in the control *** were no deaths in either ***:iMRI-assisted stereotactic biopsy can confirm the target position and adjust the puncture path in real *** to the traditional stereotactic biopsy technique,the iMRI method has a higher positive diagnostic rate,though surgical trauma and complications have no significant difference.
